Genome or Connectome?

in News, Pop Culture
March 22nd, 2011

Sebastian Seung is a professor of computational neuroscience and physics at MIT. His research in the neuroscience field involves “connectomes,” or the map of connections between and among neurons. The endeavor of investigating and mapping connectomes began in the 1980s and jumped off with the elucidation of the complete connectome of the worm C. elegans in 1986. While C. elegans has about 300 neurons, humans have about 10 billion neurons and ten times that number of connections. These connections can grow and change with and from neural activity and experience, combining to permutations exponentially greater that those of DNA and its four bases. Seung proposes that we “are our connectomes” rather than our genomes, implying that our thoughts, experiences, emotions, and consciousness itself may have a purely neural basis. To refrain from any more spoilers, he artfully expands and explains his hypothesis in the above TED talk that it is surely worth viewing. For a greater philosophical inquiry inspired by his ideas, is our matter all that matters?

  • Thanks for your article. I would love to say that your health insurance specialist also works well with the benefit of the actual coordinators of your group insurance plan. The health agent is given an index of benefits sought by a person or a group coordinator. What a broker will is try to find individuals or even coordinators which best match up those desires. Then he presents his suggestions and if both sides agree, the broker formulates an agreement between the two parties.
